int Imagick::getImageCompression (void)Parameters:This function takes no parameters.Return value:This function returns an integer value that matches one of the compression constants.The compression constantsare listed below:
- imagick::COMPRESSION_UNDEFINED (0)
- imagick::COMPRESSION_NO (1)
- imagick::COMPRESSION_BZIP (2)
- imagick::COMPRESSION_FAX (6)
- imagick::COMPRESSION_GROUP4 (7)

Program 1:
// Create a new Imagick object $imagick = new Imagick ( ’ https://media.engineerforengineer.org/wp-content/uploads/engineerforengineer-13.png ’ );
// Get compression $compression = $imagick -> getImageCompression(); echo $compression ; ?> Output:13
Program 2:
// Create a new Imagick object $imagick = new Imagick ( ’ https://media.engineerforengineer.org/wp-content/uploads/engineerforengineer-13.png ’ );
// Set compression to COMPRESSION_DXT1 $imagick -> setImageCompression (imagick::COMPRESSION_DXT1);
// Get compression $compression = $imagick -> getImageCompression(); echo $compression ; ?> Output:3
